The United States is to announce that all importers of Iranian oil will have to end their imports shortly or face US sanctions, a report says.

US Secretary of State Mike Pompeo the alleged architect of the so-called zero tolerance policy will make the announcement on Monday,The Washington Postreported Sunday, citing twoState Department officials.

The administration of President Donald Trump left a multi-lateral nuclear agreement with Iran last May. Afterwards, Washington re-imposed the sanctions that had been lifted under the accord.

Last November, the US enforced sanctions targeting the Islamic Republics banking and energy sector,however, it grantedwaiversfrom the bans to eight major importers of the Iranian oil, fearing market instability including China, India, Japan, South Korea, Taiwan, Turkey, Italy and Greece.

Now, Pompeois expected to declarethat the State Department will not be exempting the importers of Iranian crude or condensates beyond May 2, which is the deadline for renewing the waivers.

A senior State Department official said Washington was going ahead with the decision because the conditions to not grant any more SREs have now been met, pointing to significant reduction exceptions Washington's term for the waivers.

Officials cited by the daily claimed that this time around, market would avert disruptions as Saudi Arabia and the United Arab Emirates (UAE) had given commitments to increase supply.

Despite the alleged assurances, benchmark Brent crude oil futures rose by as much as 3.2 percent to $74.30 a barrel, the highest since November 1, in early trading on Monday in reaction to expectations of tightening supply, Reuters reported. US West Texas Intermediate (WTI) futures climbed as much as 2.9 percent to $65.87 a barrel, its highest since October 30.

Since his inauguration in 2016, Trump has been rallying the two countries, its closest allies in the Persian Gulf region, around an anti-Iran drive. Tehran has warned the region's countries against falling for the US ploy, saying it threatens to further alienate regional countries and trigger more tensions.

A senior official, meanwhile, referred to Pompeo as the person who originated the so-called policy of zero tolerance, noting, He has executed this policy in tight coordination with the president every step of the way.

Since Trump took office, the US has been leading more antagonistic policies towards Iran under the banner of maximum pressure. The US president claims the drive seeks to initiate negotiations leading to a better nuclear deal.

The US withdrawal from the historical 2015 accord, officially known as the Joint Comprehensive Plan of Action (JCPOA), came despite marathon negotiations leading to the accord's conclusion, which had been mediated by the European Union.

Both the departure and the reinstatement of sanctions came while the accord has been ratified in the form of a United Nations Security Council resolution.

All the other parties to the JCPOA, namely the UK, France, Russia, China, and Germany have strongly condemned the US actions over its unilateralism and violation of international law.

The US says its envisioned agreement would also be addressing Irans regional policies and missile activities. Tehran has strongly warned Washington against trying to interfere in its domestic and political affairs, and has vowed to resolutely pursue its missile program in line with its inalienable right to enhance its defensive prowess.
